Best energy consumption - International Cement Review

The most important first step in controlling energy consumption is to be aware of the relative importance of the process areas where most energy is consumed. Figure 2 shows a typical breakdown of electrical energy consumption at a cement plant. The most obvious area for attention is that of grinding, both raw and cement.

Jun 01, 2015  As result, for each 1500-kW raw material grinder and 3500-kW cement grinder, the amount of energy saved due to reduction in energy consumption was about 6.3 kJ/(kg cement) and 11.6 kJ/(kg cement) per year, respectively. On the other hand, the increase in production capacity means that the time which the grinders are needed to be in operation ...

Energy Consumption in Production of Concrete

Aug 28, 2017  The production of 1 m³ of concrete requires 2,775 MJ of energy. This energy comes mostly from oil burning, which generates CO2. 2.775 MJ of energy is produced by 0.37 barrels of oil. Saving concrete, e.g. by adopting appropriate building solutions, means therefore not only reducing fossil fuels consumption, but also pollutant emissions.
